Abstract

A fuel delivery system for an engine includes a fuel rail, a fuel injector, and a clip. The fuel rail has a cup that defines an opening. The fuel injector has an upper end that is disposed within the opening such that the cup and fuel injector are axially aligned. The clip is secured to the fuel injector and engages the cup to orient the fuel injector radially relative to the cup. The clip has a tab that extends outward relative to the fuel injector. The tab defines a central orifice that is configured to receive a fastener. The fastener is configured to mount a wire harness.

Claims (27)

1. A fuel delivery system for an engine comprising:

a fuel rail having a cup that defines an opening;

a fuel injector having an upper end that is disposed within the opening such that the cup and fuel injector are axially aligned;

a clip secured to the fuel injector and engaging the cup to orient the fuel injector radially relative to the cup, the clip having a tab that extends outward relative to the fuel injector, the tab defining a central orifice configured to receive a fastener configured to mount a wire harness; and

a wire harness having a fastening device that engages the central orifice to secure the wire harness to the clip.

2. The fuel delivery system of claim 1 , wherein the fuel injector includes an electrical receptacle that protrudes outward from the fuel injector.

3. The fuel delivery system of claim 2 , wherein the electrical receptacle is substantially perpendicular to the tab.

4. The fuel delivery system of claim 1 , wherein the tab is disposed below and spaced apart from the fuel rail.

5. The fuel delivery system of claim 1 , wherein an exterior surface of the cup defines a notch and the clip engages the notch to orient the fuel injector radially relative to the cup.

6. The fuel delivery system of claim 5 , wherein the clip has a first prong that extends axially from the fuel injector to the cup and engages the notch to orient the fuel injector radially relative to the cup.

7. The fuel delivery system of claim 6 , wherein clip has second and third prongs that straddle the first prong and engage a lower surface of the cup.

8. The fuel delivery system of claim 1 , wherein the clip is secured to the fuel injector via a keyed engagement to prevent relative rotation between the clip and fuel injector.

9. A fuel delivery system for an engine comprising:

a fuel injector configured to engage a fuel rail cup; and

a clip secured to the fuel injector and configured to engage the fuel rail cup to prevent relative rotation between the fuel injector and the fuel rail cup, the clip having a tab that extends outward relative to the fuel injector, wherein the tab is configured to receive a fastener that is configured to mount a wire harness, and wherein the tab is disposed below and spaced apart from the fuel rail cup.

10. The fuel delivery system of claim 9 , wherein the tab defines a central orifice, and wherein the fuel delivery system further comprises a wire harness having a fastening device that engages the central orifice to secure the wire harness to the clip.

11. The fuel delivery system of claim 9 , wherein the fuel injector includes an electrical receptacle that protrudes outward from the fuel injector.

12. The fuel delivery system of claim 11 , wherein the electrical receptacle is substantially perpendicular to the tab.

13. The fuel delivery system of claim 9 , wherein the clip engages a notch defined on an exterior of the fuel rail cup to orient the fuel injector radially relative to the cup.

14. The fuel delivery system of claim 13 , wherein the clip has a first prong that extends upward from the fuel injector to the cup and engages the notch to orient the fuel injector radially relative to the cup.

15. The fuel delivery system of claim 14 , wherein clip has second and third prongs that straddle the first prong and engage a lower surface of the cup, wherein the second and third prongs are configured to generate a biasing force on the cup to absorb combustion energy that is translated to the fuel injector.

16. The fuel delivery system of claim 9 , wherein the clip is secured to the fuel injector via a keyed engagement to prevent relative rotation between the clip and fuel injector.

17. A clip configured to secure a wire harness to a fuel injector and to orient the fuel injector radially relative to a fuel rail cup comprising:

a central body defining a slot that is configured to engage the fuel injector to secure the clip to the fuel injector;

a prong extending upward from the central body and configured to engage the fuel rail cup to orient the fuel injector radially relative to the fuel rail cup; and

a tab that extends outward from the central body, the tab defining a central orifice that is configured to receive a fastener for mounting a wire harness.

18. The clip of claim 17 further comprising second and third prongs that straddle the first prong, wherein the first and second prongs are configured to engage a lower surface of the cup and to generate a biasing force on the cup to absorb combustion energy that is translated to the fuel injector.
